How DuPont Pioneer is Adding Jobs

Thanks to Automation Researchers at DuPont Pioneer’s labs have cut years off the research and development time needed to get new plant breeds on the market. Because of automated equipment, tens of millions of tests are performed in the Johnston, Iowa, labs each year to deliver information to plant breeders in the greenhouses.

“Ten years ago, we were doing tenfold less than we are today. And it was costing us in the neighborhood of 10 times more,” Jason Abbas, director of global production genotyping at DuPont Pioneer, told The Des Moines RegisterRead more


To Fungicide, or Not to Fungicide

That is the question. When margins are tight, some growers may choose to forgo a fungicide application. However, that decision shouldn’t be made without scouting the fields first. lose ties to agriculture.

“We are looking at the lower part of the plant and trying to make a determination. Do we see northern [leaf blight]? Do we see gray [leaf spot]? Do we see any pathogens showing up?” said DuPont Pioneer Account Manager Tory Putnam. “If we do, we can route those fields for a later application." …Listen more

It Mite be a Hot One

Spider mites, which use needle-like stylets to rupture leaf cells and drink the leaf contents, thrive in hot, dry environments. Depending on the temperature, spider mite development takes between five and 20 days, speeding up when temperatures are hot—95° or warmer—and slowing down in cooler temperatures. The economic loss caused by the arachnid varies, but has been documented as high as 47 percent in corn grain…Read more


Corn Yield, After Dark

Above-average night temperatures during reproductive growth can reduce corn yield through both reduced kernel number and kernel weight. Higher night temperature increases the respiration rate in corn, requiring more sugar for energy and thus making less sugar available to deposit in the kernel…Read more
